Theupper-outer sash member is designated `as a wholeby numeral 25, and is 'composed of right and left hand stiles 262 and 26b having formed fthereonfribs 27a and'27b respectively whichare engageable with the guide grooves C2, D2. rThe upper eXtremitiesof stlles 26a and 26bfare bi-furcated as at 28a and 28b to afford clearance spaces in and between which areanchored one end each of chains orcords the other terminals whereof arerattached to the Vcoiinterweight-s H3 and I-I nThe lower ends of' the stiles262 and 262 are provided at their inner faces with sidewiseamd outwardly flaring recesses 292-and29b of which the left hand one is visible in Figs. IX, and XVII- XXII. VThese recesses are covered up by a lower cross rail 302 preferably of angular formation and vaffixed to the inner or room side of the stiles26a and 2'6". Slaand 31b are .upper inner-land outer top rails secured to the said extremities of the stiles .26a and 26b on the opposite sides of the bifurcations '282 and 28h, leavinga space 32 therebetween, lhereinafter more fully referred to.

SSaandBSb respectively denote rightand left hand lip-strips projecting inwardly in opposed relation from the inner or roomfaces of the stiles .26aand 26b and extend upwardly a certain distance from the upper j From the outer faces of the last named stiles extend in opposed relation, inwardly, similar right and left hand-strips,311a and 34h commencing at points adjacent the lower edge of top rail 31b and extend downwardly a given distance therefrom. From'Fig. II it willbe seen that the upper and lower transverse ends of strips 330L and B42 terminate substantially in the samehorizontal plane. vThus itwill beseen that Ithe above mentioned members which jointlyeompose the outer sash are immovably securedtogether'to form a rigid frame.

The part of the upper outer sash member which is tiltable within the sliding one just described is referred to in its entirety by the numeral and consists of right and left stile members 51L and 51b respectively. The opposed inwardly turned sides of these members are rabbeted as indicated at 51C for 51, and at 51d for 51h, to afford receiving ledges or grooves for the upper window pane K1. Overlying the outwardly or eXteriorly facing narrowV portion of stiles 51a and 51b are right and left glass retaining strips 52a and 52"respectively. The lower extremities of the stiles 51"L and 51b are undercut as seen most clearly at 58 on the right hand side of Fig. X, in order to receive an inner lower cross rail 542. The latter is rabbeted as at bto lform a continuation and lie in :the same 4plane with .the rabbets 51c .and 51d to con- '.tinue the glass retaining ledge. The vglass retaining strip at the bottom of the tilting sash is indicated byzthe numeral 54.

. .Again-st the undcrsides orbottom faces-of thecross :rail 542 and strip 54C abuts another strip 55a of the same wic th as those last referred to. From the opposite outer end portions of the strip 55a project sidewise outwardly therefrom right and left horns 55b andc. The-exteriorly turned faces of these horns are bevelledas will be seen to best advantage at 551 on the lower right hand side of Fig. X. The bevels `of horns 55 and 55c afford easy entrance andengagement into and with the straight outer Vor rear walls of recesses 292 and 291. In a like manner the straight 4or perpendicular ends of said horns 55b and 55,C cofact with the inclined side walls ofthe recesses 282L and 29b to locate or centralize the lower portion of tiltable sash member'O within the sliding sash member 25.

' The upper extremitieslof stiles 51L and 51" are reduced in width so asto leave shoulders andten'on-lilre projections 51e and 51f there on respectively right and left. A topcrosa rail.melllbe-56Et is attached by its outer reduced end portions to the inner or room faces of the tenons 51e and 51f, which member 56a in conformityv with the stiles 51, '51"and 54,

is provided with a glass pane receiving rabbet5'6". The glass retaining strip 56c is affixed to the exterior of said tenons 51e and 51f and the combined thickness of members 56a and 56is of such dimensions asto have a sliding lit in a vertical direction in and throughthe spaced?l previously referred to.

Lip strips aand V57h respectively right and'left, are secured to the upperhalf 'of the innerroom faces of the stiles 51a and 51 and overhang the latter Voutwardly sidewise to an extent equal to the width of the stiles 26?t and 262 of the sliding sash. Other lip strips 58al and 58b respectively right and vleft are fastened to the lowerouter faces of stiles 51a and`51b and reach sidewise outwardly beyond the same an amount equalto the overhanging width of the before named strips 57a and 57h, being also flush with the inner side edges of the glass retaining strips 52a and 52h. A lilling strip 54nd of a depth equal to that of the strips 54a or 54 and 55a is aiiixed to the eX# terior faces of the 'latter and 54C, projecting sidewise beneath the overhanging portions ot the lipA strips 58a and 58h. `The last. named strips extendupwardly along stiles 52a and i 52b to a level somewhat below the lowerends of the lip strips 57 and 57h. The distances between the top ends of strips 58a and 58h, and bottom endsy or' lip strips 5T and 57 are approximately equal to the fore and aft thickness of the stiles 2Sa and 26" plus a suitable clearance to enable the member 50 to be freely tilted into the position illustratedby Fig.

, ly beneath the lower transverse ends of the lip strips 34a and 34hv of the sash 25. From the foregoing', it is evidentthat the before named members composing the inner sash 50 are unyieldably 'secured one to the other toY form a frame which is rigid.

The position assumed by sash 50;when the same is tilted back or vertically, is indicated in Fig. V wherein is represented the displaced condition of said sash 50 relatively to the other sash 25, i. e. into the plane of movement ,of the last namedsash'member. To bring the tiltable'sash member 50 into regis-` ter with or in planar alignment with slid# able sash member 25, illustrated in the upper right hand portion of Figs. III and IV, so that rails 56a and 56C are received within the space 32 and horns 55e and 55d enter recesses 29a vand 29h, it becomes necessary to lift sash 50 with respect to the sash member 25, at which time the upper transverse edges of lip strips 58a and 58h abut the lower similar edges of strips 34a and 34;b on the sliding sash, both sets of these edges being bevelled downwardly and rearwardly so as to shed rain and moisture. A

The means for looking the sash member 50 in V`its highest position within the member 25, consists as depicted in Figs. I Y and VI of latches 6,0 pivoted at 6l to the inwardly facing sides of the inner lip strips 33a and 33b of said member 25.- At such times as these latches are in locking positionthey it snugly in between the upper transverse ends` `of strips 33a and 33b and the lower similar ends of lip strips 57a and l57", thus acting'as'struts or braces in 'preventing the member 50 from droppingv down.. When it is desired to dis'- place the'meinber 50 relatively to the member 25, the said latches 60 are swung downwardly themanipulation of each of the latches 60. It

will be noted that the corners of they latches are rounded as atti()a and o()b to aiord clearance and ease of movement into and out of locking position. c

sashcs are alike except that the positions of cross rails 30a and 3()b are reversed. shown, the upper rail 302L is aiiiXed to the lower inner sides of the Stiles 26a and 26h while the other cross-rail 30b is securedto the upper and outer sides of the stiles of the lower inner sash. When the lower inner and upper outer sashes are in the closed'position depicted in Figs. I and II raily 30b overlaps and is contacted at the underside thereof by cross-rail 30a. The locking device which clamps the sashes together is composed of the usual parts 62a and 62b of which part 62a is carried by rail 30a and part 62b vby the other rail 30". The numerals 63aM and 63h denote operating handles of which handle 63a` is attachedto rail 30a while the other handle 63b is fixed to the rail 30h.

In describing the operationof the device, it will be assumed that the parts are4 in theposition shown in Fig. II and that it is desired to clean the glass of the tiltable member 50. In this case. the latches 60 are operated to release the tiltable from the slidable member and then the loclr 621-62b isoperated to disconnect the upper from the lower sash. The latter sash is then pushed upward while the upper sash is moved down into lthe position shown in Fig. V With the latches 60released, the slidable member 2 5 is pulled upward slightly to displace it with respect to the tiltable member 50. The last named member can then be swung to the position shown in Fig. VI and both sides of the glass pane washed and, cleaned or reached Jfor purposes of repair or replacement, from the inside of the room. The same operation in general will take place when the lower sash is to be manipulated to open the panecarrying portion thereof. When the cleaning, f repairing or other operations are completed, the tiltable member is swung back into the plane of the slidable member and then they are moved relative to each other in the same plane to bring the one into engagement with the other. The coacting bevelled or sloping surfaces before referred to when engaged will tend to keep the `two portions of the sash together and prevent their rattling. The latches 60 will hold them` in their normal position, one nested o1` housed within the other. It will be noted that there is no positive connection between the two portions of each sash and consequently there is no hardware required except the latches and the lock 62a. i
